An interview with Wards Auto where the business manager of the DOE's Kentucky-Argonne Battery Manufacturing Research and Development Center explained that it takes about ten years to put a battery innovation into production and all of today's EVs are powered by technologies that were developed at least a decade ago. An article from National Defense which predicts that lithium-ion battery research will soon hit a brick wall because batteries can only be as small and lightweight as their materials allow and immutable laws of physics and chemistry limit the number of electrons that can be stored in a given mass of battery material. An article in Nature that discussed ways nanotechnology can improve battery performance by increasing surface area, but took pains to explain that nano-materials must be produced in carefully controlled environments and the high cost of manufacturi...
